Modding kiiro Keon to work with power supply socket instead of Battery

Nevermind, it started again today and it also charges normally. :upside_down_face:

There is no warranty and battery life is so awful that I pretty much need to mod it to make it useful again. However, I lack tools and experience in doing these things so it is quite a hurdle to overcome.

Anyway, thanks for the help :slight_smile:

Great that it is working again!

You could also use wiring and wrap it around the bridges of the connector and isolate it using electrical tape. But I would definitly worry about the wiring coming loose.
Hotglue would also work as solution for isolation, but that creates a mess and may also come loose over time as well as create a mess.
However this would be mostly toolfree.
Soldering isn’t required but highly recommended.

The battery life really is horrible, that is why so many people modded their keon to use it with a power supply instead.

Yeah, after looking around a little on reddit my best guess is that debris in the power jack made it non-functional temporarily.

I thought that u had to have a soldering iron at least, which I don’t. Also, I have never soldered anything. When I looked around a little in the thread, there seems to be another solution - to cut the cords to the battery and clamp them together with a new powerjack like @IggydB did.

I have used clamps and a drill before, so this option seems like the easiest. Maybe I’ll try it to begin with, if I fail for some reason I can maybe try soldering in new wiring instead.

Btw, which clamp size should I preferably use in cm? Also, I would appreciate recommendation for compatible power jacks & ac adapters to go with in EU.

If you mean the Wago clamps, those are usable from small DIY Projects like this up to proper house electrics.
They also have some for inline connections. Those would be a lot more space saving. But the ones you saw in IggydBs’ post will work perfectly fine as well, if you remove the battery anyways.
You can probably source these or similar in your local Hardware Store.
However these aren’t designed for stranded wires like these. (A single line has many thin coper Wires)
You can use them, but make sure they clamp down and hold the wire in place, as well as none of the small copper strands being outside the clamp to avoid accidental shorts.
Twist the loose copper strands together to give them a bit more strength before putting them in the clamp.
Don’t get connectors where you push the cables in, as you would have to crimp or solder the copper strands together for it to work.

I used this power supply before without any issues. You will find it from many different brands. These are generic “no name” devices. So don’t expect high quality from it.
Voltage was always within 0.1V of what was displayed and is stable for as long as you aren’t at either highest or lowest voltage possible for other projects.

The PowerJack, that depends on your Power Supply. Can’t really recommend a specific one. But most universal Power Supplies should work if they support 15-16 Volt and at least 3 Ampere. Less Ampere may work, but I haven’t measured the actual power it needs.
You may even be able to find a Notebook Power Supply that provides the Voltage needed or you may already have one without noticing.
The most common Power Jack is 2.1x5.5MM. But that depends on the Power Supply you have.

You may also need a few cm of wires. So if sourcing the Power Jack, you could look out for them coming with wires.
You can of course also canibalize the cable of an unused charging cable or similar. I wouldn’t use a USB-A cable, as they may be to thin.
I am not an electrician, so take that advice with a grain of salt.

Europe is huge and for small orders like these, you would have to pay shipping if it goes over boarders or wait for weeks. That is why I am just sending generic Amazon Links for reference, as all the components are pretty easy to find online or maybe even in Hobby/Hardware stores.

When drilling, keep in mind. The Keon is made out of plastic and plastic melts. Drilling produces quite a bit of heat and melt together with the drillbit if not cooled.

Yeah, I was thinking of using something like this instead: https://www.amazon.com.be/-/en/COXB370300-Connection-Terminals-Practical-Installation/dp/B09446BM2V?language=en_GB

Should work, and being able to screw down the wire seems more secure than using only a plastic clamp.

Thanks for the specs of the other stuff, I will try to find the appropriate parts from trusted brands available at local vendors. Preferably a Power jack with some wiring attached, so you can make a direct connection. I don’t really trust no-name brands from amazon, so I avoid them if possible.

Wago is a really popular brand for electrical work.
With screw in terminals you need to be careful with stranded wires, as the screw only goes down the middle of the opening and it is easy to have copper strands move out of the way and be loose.
